There's only one Source Four® -- the fixture that changed the lighting industry.

Source Four combines the energy-saving power of the patented HPL lamp (not included), with a dichroic reflector and optical-quality lenses, for the coolest beam on the market. That means your gels, patterns and shutters last longer and your performance space stays cooler. No other light offers such optical brilliance. Source Four's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field. The EDLT lens tube option for 19°, 26°, 36° and 50° field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections. Rated for up to 750 watts, the Source Four is perfect for punching through saturated colors and performing the longest throws. Ultra-efficient for more lumens per watt: at 575 watts the Source Four literally outshines 1000W ellipsoidals. And at 750 watts, well, no point comparing - there are no other fixtures in its class.

Source Four-brand lighting fixtures are the first choice of entertainment-lighting professionals worldwide. No other lights provide such lighting punch while keeping heat generation to a minimum and providing radical energy savings. And Source Four optics have yet to be surpassed in imaging excellence. These are the world's best lights - with over 1.7 million units shining brightly in entertainment venues across the globe - outperforming and outlasting all others.
